By CIOReview | Tuesday, June 16, 2015

FREMONT, CA: Chelsio Communications – a provider of Ethernet adapters for virtualized data centers, cloud service installations, and cloud computing environments – announced that its T5 iWARP RDMA over Ethernet adapters now fully support NVIDIA GPUDirect RDMA technology. It delivers high performance Ethernet connectivity solutions to address customers’ most demanding data analytics and scientific applications.

NVIDIA GPUDirect RDMA as a key component of NVIDIA Tesla Accelerated Computing Platform accelerates data analytics, deep learning, and scientific computing. It eliminates CPU bandwidth and its limitations using direct data transfers between GPUs and other PCIe devices bypassing the host processor and memory.

"We are pleased to support the leading accelerated computing platform with iWARP, and help NVIDIA bring new levels of computational performance to data analytics and HPC customers. Our iWARP RDMA solution is recognized as an easy to use, industry-leading connectivity fabric for RDMA using standard Ethernet. We look forward to increased adoption of Ethernet in high performance applications," said Wael Noureddine, vice president, technology, Chelsio. 

Benefits of using NVIDIA GPUDirect RDMA integrated with Chelsio’s T5 adapters include: four times latency reduction across the message size range, five times bandwidth improvement for large messages with Chelsio T5 40GbEiWARP compared to standard 40G server NICs, superior throughput of Chelsio’s 40G iWARP RDMA compared to alternative RDMA over Ethernet protocols.

"With the addition of 40Gb Ethernet and other advanced technologies to the Tesla Accelerated Computing Platform, NVIDIA continually provides an expanded range of flexible, ultra-high performance computing solutions for HPC and enterprise customers. Enabling direct data transfers between Chelsio devices and NVIDIA GPUs, iWARP with GPUDirect RDMA improves performance by maximizing bandwidth while minimizing latency," said Duncan Poole, director, Platform Alliances, NVIDIA.

Chelsio’s Terminator 5 ASIC offers: high performance, robust third-generation implementation of RDMA (Remote Direct Memory Access) over 40GB Ethernet, the Internet Wide Area RDMA Protocol- iWARP, end-to-end RDMA latency as InfiniBand, using standard Ethernet infrastructure.
